get my (future) kids obsessed with 'Singin In The Rain'

I’m thinking about bringing my future kids up on musicals =) I watched heaps when I was little (as well as lots of other films) and just think they give you more of an appreciation for music – or even just for old movies – I DON’T want them to be like those people who say ‘Why are just suddenly, like, singing?’
The answer is BECAUSE THEY CAN! Gosh – just get over it.
Ok – I’m just starting to rant now so I think I’ll stop, lol – but they have to love ‘Singin in the Rain’ if they don’t I’ll feel like a failure as a mum, lol
